Description
CT-122F 16 channel digital input/24VDC/ Sink type
1 Module features
*the module supports 16 channels digital input, supports sink input, and input
voltage is 24VDC.
*the module can collect digital output signal of field equipment (dry contact or
active output).
*the module can be accessed to 2-wire or 3-wire digital sensor.
*the internal bus and field input of the module use opto-isolator.
*the module supports the input signal holding function, and the holding time
can be set.
*the module carries 16 digigtal input channels with LED indicator on each
channel.
*supports counting function, by adding counting sub-module.
*each input channel of the module supports a 32-bit counter with the counting
frequency <200Hz.
*the module can set the digital signal input filtering time and the byte
transmission order of the counter.
*each channel of the module can set the counting mode and counting direction
independently.
